Erratum to Analysis of factors related to non-sentinel lymph node metastasis in 296 sentinel lymph node-positive Chinese breast cancer patients

In the published article1, some errors appeared in the use of abbreviations. Sentinel lymph node should be referred as SLN instead of NSLN, non-sentinel lymph node should be referred as non-SLN instead of non-NSLN. Only in the Figure 1 and Table 1, NSLN means non-SLN. We apologize for the errors and for any confusion it may have caused
